Description

Technical Field

[0001] The present invention relates to the technical field of angle and azimuth adjustable antennas, and more specifically, to a television receiving antenna that can be adjusted at multiple angles. Background Art

[0002] A television receiving antenna is an important part of wireless television signal reception and is the gateway for radio waves to enter the cable television system. There are two types of antennas: passive antennas and active antennas. Active antennas can enable the antenna system to achieve high-gain and high-signal-to-noise ratio reception. However, during the use of the antenna, the signal reception is often limited by its orientation.

Detailed Description of the Invention

[0042] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0043] A multi-angle adjustable TV receiving antenna, comprising

[0044] Base 1,

[0045] Horizontal rotation block 2, the horizontal rotation block 2 is rotatably arranged outside the base 1;

[0046] Receiving antenna cover 3, the receiving antenna cover 3 is arranged outside the horizontal rotation block 2;

[0047] A swing drive is arranged inside the horizontal rotation block 2, and the swing drive can drive the receiving antenna cover 3 to swing at an angle.

[0048] In this technical solution, while the receiving radome 3 changes its vertical angle, its horizontal angle also changes. At this time, the receiving radome can search for signals at multiple angles until the best signal source is received, expanding the search range and thus improving the efficiency and effect of search and reception.

[0049] Specifically, the swing drive includes a rotating column 4, and the rotating column 4 is arranged inside a rotating cavity 5 opened inside the horizontal rotating block 2;

[0050] A curve groove 6 is opened on the circumferential outer wall of the rotating column 4, a swing groove 7 is opened on one side of the horizontal rotating block 2, the swing groove 7 is communicated with the rotating cavity, and a swing rod 8 is arranged inside the rotating cavity. The swing rod 8 passes through the swing groove and the part of the swing rod passing through the horizontal rotating block is fixedly connected with the receiving radome 3;

[0051] One end of the swing rod 8 is provided with a convex block 9, and the convex block 9 is slidably connected with the curve groove 6.

[0052] In this technical solution, when the rotating column 4 rotates inside the rotating cavity, the convex block 9 moves along with the curve groove, causing the swing rod 8 to rotate around its connection with the rotating cavity, so that the receiving radome 3 can swing and change.

[0053] Furthermore, the swing rod 8 is arranged in an L-shaped structure, and the middle part of the swing rod 8 is rotatably connected with the side wall of the rotating cavity through a pin shaft.

[0054] Still further, the curve groove 6 is arranged in an annular inclined structure around the outer wall of the rotating column 4, and the curve groove forms a closed loop.

[0055] Even further, a synchronous groove 10 is opened inside the base 1, a driving bevel gear 11 is rotatably arranged on one side inside the synchronous groove 10, and the rotating shaft of the driving bevel gear 11 passes through the inner wall of the synchronous groove 10 and extends into the rotating cavity 5 and is coaxially connected with the rotating column 4.

[0056] It should be noted that a reversing bevel gear 12 is also arranged inside the synchronous groove 10. The outer wall of the reversing bevel gear 12 is meshed with a synchronous bevel gear 13. A sleeve 14 is sleeved in the middle of the synchronous bevel gear 13, and the sleeve 14 is rotatably arranged on the rotating shaft of the driving bevel gear 11;

[0057] One end of the sleeve 14 passes through the inner wall of the synchronous groove 10 and extends to the outside and is fixedly connected with the horizontal rotating block 2.

[0058] In this technical solution, through the arrangement of the reversing bevel gear 12, the driving bevel gear 11 and the synchronous bevel gear 13 can rotate in different directions at the same time. Therefore, the receiving radome 3 can swing while rotating, so as to move to a suitable receiving position, shortening the search time and further improving the efficiency.

[0059] It should be noted that a locking drive groove 15 is also provided inside the base 1. An intermittent rotating wheel 16 is arranged inside the locking drive groove 15, and a plurality of card slots are evenly arranged on the outer side of the intermittent rotating wheel; one side inside the locking drive groove 15 is rotatably provided with an intermittent pushing block 17 through a pin shaft. One end of the intermittent pushing block 17 is rotatably provided with a push rod 18 through a pin shaft, and the push rod 18 can be inserted into the card slot.

[0060] The other end of the intermittent pushing block 17 is provided with a roller 19, and a driving wheel 20 is rotatably arranged inside the locking drive groove 15. The roller abuts against the outer wall of the driving wheel 20.

[0061] A locking hook 21 is arranged on one side of the intermittent pushing block 17, and the locking hook 21 can be inserted into the card slot.

[0062] A machine cavity 22 is opened outside the locking drive groove 15. A motor 23 is arranged inside the machine cavity 22. The output shaft of the motor 23 passes through the inner wall of the machine cavity 22 and extends into the locking drive groove 15 and is sleeved with the driving wheel 20.

[0063] The intermittent rotating wheel 16 is coaxially connected to the rotating shaft of the driving bevel gear 11.

[0064] In this technical solution, through the movement of the intermittent pushing block 17, the intermittent rotating wheel 16 is driven to rotate intermittently and slowly through the push rod 18, thereby leaving enough time to find a suitable position for the receiving radome 3. At the same time, due to the setting of the locking hook 21, the intermittent rotating wheel 16 can be limited after the position is adjusted, so that the receiving radome 3 can be stabilized at the current position, avoiding the situation that the receiving radome rotates due to external forces in bad weather.

[0065] In addition, the cross section of the card slot is trapezoidal, and the width of the card slot gradually becomes smaller as it approaches the edge of the intermittent transmission wheel.

[0066] In this technical solution, each time the push rod 18 can be accurately meshed and pushed, and at the same time, the locking effect of the locking hook 21 is improved.

[0067] In addition, one side of the driving wheel 20 is provided with a wavy notch.

[0068] In this technical solution, the intermittent pushing block 17 can swing better inside and outside, so that the functional effects of the push rod 18 and the locking hook 21 are further improved.

[0069] In addition, a spring A 24 is connected and arranged on the outer side of the push rod 18, and a spring B 25 is connected to the outer side of the intermittent pushing block 17, and both are fixedly connected to the inner wall of the locking drive groove 15. The spring A can push the push rod into the card slot, and the spring B can pull the intermittent pushing block to rotate and move it away from the intermittent rotating wheel.

[0070] In this technical solution, the spring is arranged such that the push rod 18 can always be in contact with the intermittent rotating wheel 16, and the intermittent push block 17 can always be in contact with the outer wall of the driving wheel 20, ensuring the pushing effect of the push rod on the intermittent rotating wheel and the locking effect of the locking hook on the intermittent rotating wheel.

[0071] When the multi-angle adjustable TV receiving antenna is needed, the controller drives the output shaft of the motor 23 to rotate, driving the sleeved driving wheel 20 to rotate. When at the notch of the driving wheel 20, due to the pulling effect of the spring B25 on the intermittent push block 17, the intermittent push block 17 moves away from the intermittent rotating wheel. At the same time, the locking hook disengages from the card slot, and the push rod 18 moves in the corresponding card slot and finally disengages from the card slot where it is located at that time. Under the action of the spring A24, the push rod has a tendency to rotate towards the locking hook and finally snaps into the next card slot on the side close to the locking hook.

[0072] When the driving wheel continues to rotate so that the roller abuts against the larger arc surface of the outer diameter of the driving wheel, due to the abutting effect of the driving wheel on the roller, the side of the roller facing the intermittent rotating wheel 16 rotates. Finally, the push rod pushes the intermittent rotating wheel to rotate by a step angle, and then the locking hook snaps into the corresponding card slot to lock the intermittent rotating wheel.

[0073] Of course, in the actual use process, in order to ensure the rotation accuracy of the intermittent rotating wheel, the intermittent rotating wheel can be connected to the wall of the locking drive groove at its bottom through a one-way bearing, so that the intermittent rotating wheel can only rotate in one direction.

[0074] At this time, the driving bevel gear 11 rotates intermittently, driving the coaxial rotating column 4 to rotate. At this time, the convex block 9 slides in the rotating cavity 5 on the rotating column 4, prompting the swing rod 8 to swing, thereby driving the receiving antenna cover 3 to swing.

[0075] At the same time, the rotation of the driving bevel gear 11 causes the reversing bevel gear 12 to rotate. The rotation of the reversing bevel gear 12 drives the synchronous bevel gear 13 to rotate. The sleeve 14 on the synchronous bevel gear 13 does not rotate synchronously with the driving bevel gear 11. Therefore, when the driving bevel gear 11 rotates forward, through the switching of the reversing bevel gear 12, the synchronous bevel gear 13 rotates in reverse, so that the sleeve 14 drives the horizontal rotating block 2 to rotate, thereby driving the receiving antenna cover 3 to rotate, so that the antenna in the middle of the receiving antenna cover 3 rotates horizontally. Through forward and reverse rotation, the antenna position search of the semi-circular coverage area of the receiving antenna cover 3 is realized, and thus the best position for antenna reception can be quickly determined.
